Introduction

Getting Started

The PL API Docs is organized around REST. Our API has predictable resource-oriented URLs, accepts form-encoded request bodies, returns JSON-encoded responses, and uses standard HTTP response codes, authentication, and verbs.

Errors

The PL API uses conventional HTTP response codes to indicate the success or failure of an API request. In general: Codes in the 2xx range indicate success. Codes in the 4xx range indicate an error that failed given the information provided (e.g., a required parameter was omitted, a network problem, etc.). Codes in the 5xx range indicate an error with Performance Learning's servers (very rare).

Some 4xx errors that could be handled programmatically or by checking if your API Key is still valid (e.g., forbidden requests) include an error code that briefly explains the error reported.
